CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority to U.S. Provisional Application No. 62/538,538, filed on Jul. 28, 2017, which is hereby incorporated by reference in its entirety.

FIELD OF THE TECHNOLOGY

The present application relates to autonomous vehicles, and in particular, to autonomous vehicles for handling and delivering food items.

BACKGROUND

The field of fully-autonomous and/or semi-autonomous robots is a growing field of innovation. Robots are being used for many purposes including warehouse inventory operations, household vacuuming robots, hospital delivery robots, sanitation robots, and military or defense applications.

In the consumer space, handling and delivery of food by autonomous vehicles could improve society in many ways. For example, rather than spending time driving to a restaurant, a person can instead engage in productive work while waiting for an autonomous vehicle to deliver the food. With fewer vehicles on the road, traffic conditions would also improve. For example, instead of several people driving to restaurants in several vehicles, a single autonomous vehicle could deliver food to those people and thereby reduce the number of vehicles on the road. Accordingly, there is interest in developing technologies for handling and delivering food by autonomous vehicles.

DETAILED DESCRIPTION

This disclosure relates to a fully-autonomous and/or semi-autonomous robot fleet and, in particular, to robot vehicles for transporting or retrieving deliveries in either open unstructured outdoor environments or closed environments. In one aspect, the present disclosure provides systems and autonomous vehicles for receiving food orders for heated food items to be delivered to delivery destinations, where the food items are heated on the autonomous vehicles en route to the delivery destination. In this manner, food items delivered to a destination can be fresher and less susceptible to problems with existing heated delivery, such as dryness from overheating or sogginess from steam, among other problems.

Provided herein is a robot fleet having robot vehicles operating fully-autonomously or semi-autonomously and a fleet management module for coordination of the robot fleet, where each robot within the fleet is configured for transporting, delivering or retrieving goods or services and is capable of operating in an unstructured open or closed environment. Each robot can include a power system, a conveyance system, a navigation module, at least one securable compartment or multiple securable compartments to hold goods, a controller configurable to associate each of the securable compartments to an assignable customer a customer group within a marketplace, or provider and provide entry when authorized, a communication module and a processor configured to manage the conveyance system, the navigation module, the sensor system, the communication module and the controller.

As used herein, the term “autonomous” includes fully-autonomous, semi-autonomous, and any configuration in which a vehicle can operate in a controlled manner for a period of time without human intervention.

As used herein, the term “fleet,” “sub-fleet,” and like terms are used to indicate a number of land vehicles, watercraft or aircraft operating together or under the same ownership. In some embodiments the fleet or sub-fleet is engaged in the same activity. In some embodiments, the fleet or sub-fleet are engaged in similar activities. In some embodiments, the fleet or sub-fleet are engaged in different activities.

As used herein, the term “robot,” “robot vehicle,” “robot fleet,” “vehicle,” “all-terrain vehicle,” and like terms are used to indicate a mobile machine that transports cargo, items, and/or goods. Typical vehicles include cars, wagons, vans, unmanned motor vehicles (e.g., tricycles, trucks, trailers, buses, etc.), unmanned railed vehicles (e.g., trains, trams, etc.), unmanned watercraft (e.g., ships, boats, ferries, landing craft, barges, rafts, etc.), aerial drones, unmanned hovercraft (air, land and water types), unmanned aircraft, and even including unmanned spacecraft.

As used herein, the term “compartment” is used to indicate an internal bay of a robot vehicle that has a dedicated door at the exterior of the vehicle for accessing the bay, and also indicates an insert secured within the bay.

As used herein, the term “sub-compartment” is used to indicate a subdivision or portion of a compartment.

As used herein, the term “user,” “operator,” “fleet operator,” and like terms are used to indicate the entity that owns or is responsible for managing and operating the robot fleet.

As used herein, the term “customer” and like terms are used to indicate the entity that requests the services provided the robot fleet.

As used herein, the term “provider,” “business,” “vendor,” “third party vendor,” and like terms are used to indicate an entity that works in concert with the fleet owner or operator to utilize the services of the robot fleet to deliver the provider's product from and or return the provider's product to the provider's place of business or staging location.

As used herein, the term “server,” “computer server,” “central server,” “main server,” and like terms are used to indicate a computer or device on a network that manages the fleet resources, namely the robot vehicles.

As used herein, the term “controller” and like terms are used to indicate a device that controls the transfer of data from a computer to a peripheral device and vice versa. For example, disk drives, display screens, keyboards, and printers all require controllers. In personal computers, the controllers are often single chips. As used herein the controller is commonly used for managing access to components of the robot such as the securable compartments.

As used herein a “mesh network” is a network topology in which each node relays data for the network. All mesh nodes cooperate in the distribution of data in the network. It can be applied to both wired and wireless networks. Wireless mesh networks can be considered a type of “Wireless ad hoc” network. Thus, wireless mesh networks are closely related to Mobile ad hoc networks (MANETs). Although MANETs are not restricted to a specific mesh network topology, Wireless ad hoc networks or MANETs can take any form of network topology. Mesh networks can relay messages using either a flooding technique or a routing technique. With routing, the message is propagated along a path by hopping from node to node until it reaches its destination. To ensure that all its paths are available, the network must allow for continuous connections and must reconfigure itself around broken paths, using self-healing algorithms such as Shortest Path Bridging. Self-healing allows a routing-based network to operate when a node breaks down or when a connection becomes unreliable. As a result, the network is typically quite reliable, as there is often more than one path between a source and a destination in the network. This concept can also apply to wired networks and to software interaction. A mesh network whose nodes are all connected to each other is a fully connected network.

As used herein, the term “module” and like terms are used to indicate a self-contained hardware component of the central server, which in turn includes software modules. In software, a module is a part of a program. Programs are composed of one or more independently developed modules that are not combined until the program is linked. A single module can contain one or several routines, or sections of programs that perform a particular task. As used herein the fleet management module includes software modules for managing various aspects and functions of the robot fleet.

As used herein, the term “processor,” “digital processing device” and like terms are used to indicate a microprocessor or central processing unit (CPU). The CPU is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.

The Fleet of Robot Vehicles

Provided herein is a robot fleet 100, as illustrated in FIG. 1, having robot vehicles 101, with each one operating fully-autonomously or semi-autonomously.

As illustrated in FIGS. 3-6, one exemplary configuration of a robot 101 is a vehicle configured for land travel, such as a small fully-autonomous (or semi-autonomous) automobile. The exemplary fully-autonomous (or semi-autonomous) automobile is narrow (i.e., 2-5 feet wide), low mass and low center of gravity for stability, having multiple secure compartments assignable to one or more customers, retailers and/or vendors, and designed for moderate working speed ranges (i.e., 1.0-45.0 mph) to accommodate inner-city and residential driving speeds. Additionally, in some embodiments, the land vehicle robot units in the fleet are configured with a maximum speed range from 1.0 mph to about 90.0 mph for high speed, intrastate or interstate driving. Each robot in the fleet is equipped with onboard sensors 170 (e.g., cameras (running at a high frame rate, akin to video), LiDAR, radar, ultrasonic sensors, microphones, etc.) and internal computer processing to constantly determine where it can safely navigate, what other objects are around each robot and what it may do.

In in some embodiments, the robot fleet is fully-autonomous.

In in some embodiments, the robot fleet is semi-autonomous. In some embodiments, it may be necessary to have human interaction between the robot 101, the fleet operator 200, the provider 204 and/or the customer 202 to address previously unforeseen issues (e.g., a malfunction with the navigation module; provider inventory issues; unanticipated traffic or road conditions; or direct customer interaction after the robot arrives at the customer location).

In in some embodiments, the robot fleet 100 is controlled directly by the user 200. In some embodiments, it may be necessary to have direct human interaction between the robot 101 and/or the fleet operator 200 to address maintenance issues such as mechanical failure, electrical failure or a traffic accident.

In some embodiments, the robot fleet is configured for land travel. In some embodiments, each robot land vehicle in the fleet is configured with a working speed range from 13.0 mph to 45.0 mph. In some embodiments, the land vehicle robot units in the fleet are configured with a maximum speed range from 13.0 mph to about 90.0 mph.

In some embodiments, the robot fleet is configured for water travel as a watercraft and is configured with a working speed range from 1.0 mph to 45.0 mph.

In some embodiments, the robot fleet is configured for hover travel as an over-land or over-water hovercraft and is configured with a working speed range from 1.0 mph to 60.0 mph.

In some embodiments, the robot fleet is configured for air travel as an aerial drone or aerial hovercraft and is configured with a working speed range from 1.0 mph to 80.0 mph.

In some embodiments of the robot fleet, the autonomous robots within the fleet are operated on behalf of third party vendor/service provider.

For example, a fleet management service is established to provide a roving delivery service for a third party beverage/food provider (e.g., a coffee service/experience for a third party vendor (i.e., Starbucks)). It is conceived that the fleet management service would provide a sub-fleet of “white label” vehicles carrying the logo and products of that third party beverage/food provider to operate either fully-autonomously or semi-autonomously to provide this service.

In some embodiments of the robot fleet, the autonomous robots within the fleet are further configured to be part of a sub-fleet of autonomous robots, and each sub-fleet is configured to operate independently or in tandem with multiple sub-fleets having two or more sub-fleets (100-a, 100-b).

For example, a package delivery service is configured to offer multiple levels of service such as “immediate dedicated rush service,” “guaranteed morning/afternoon delivery service,” or “general delivery service.” A service provider could then have a dedicated sub-fleet of delivery vehicles for each type of service within their overall fleet of vehicles. In yet another example, a third party has priority over a certain number of vehicles in the fleet. In so doing, they can guarantee a certain level of responsiveness. When they aren't using the vehicles, the vehicles are used for general services within the fleet (e.g., other third parties).

In some embodiments, the robot fleet is controlled directly by the user.

In some embodiments, there will likely be times when a vehicle breaks down, has an internal system or module failure or is in need of maintenance. For example, in the event that the navigation module should fail, each robot within the fleet is configurable to allow for direct control of the robot's processor to override the conveyance and sensor systems (i.e., cameras, etc.) by a fleet operator to allow for the safe return of the vehicle to a base station for repair.

The Operating Environments

In some embodiments, the unstructured open environment is a non-confined geographic region accessible by navigable pathways, including, for example, public roads, private roads, bike paths, open fields, open public lands, open private lands, pedestrian walkways, lakes, rivers or streams.

In some embodiments, the closed environment is a confined, enclosed or semi-enclosed structure accessible by navigable pathways, including, for example, open areas or rooms within commercial architecture, with or without structures or obstacles therein, airspace within open areas or rooms within commercial architecture, with or without structures or obstacles therein, public or dedicated aisles, hallways, tunnels, ramps, elevators, conveyors, or pedestrian walkways.

In some embodiments, the unstructured open environment is a non-confined airspace or even near-space environment which includes all main layers of the Earth's atmosphere including the troposphere, the stratosphere, the mesosphere, the thermosphere and the exosphere.

In some embodiments, the navigation module controls routing of the conveyance system of the robots in the fleet in the unstructured open or closed environments.

The Fleet Management Module

In some embodiments of the robot fleet 100, the fleet includes a fleet management module 120 (associated with a central server) for coordination of the robot fleet 100 and assignment of tasks for each robot 101 in the fleet. The fleet management module coordinates the activity and positioning of each robot in the fleet. In addition to communicating with the robot fleet, fleet owner/operator and/or user, the fleet management module also communicates with providers/vendors/businesses and customers to optimize behavior of the entire system.

The fleet management module works in coordination with a central server 110, typically located in a central operating facility owned or managed by the fleet owner 200.

As illustrated in FIG. 11, in one embodiment, a request is sent to a main server 110 (typically located at the fleet owner's or fleet manager's location), which then communicates with the fleet management module 120. The fleet management module then relays the request to the appropriate provider 204 of the service (e.g., restaurant, delivery service, vendor or retailer) and an appropriate robot or robots 101 in the fleet. The best appropriate robot(s) in the fleet within the geographic region and typically closest to the service provider, is then assigned the task, and the provider of the service 204 then interacts with that robot 101 at their business (e.g., loading it with goods, if needed). The robot then travels to the customer 202 and the customer interacts with the robot to retrieve their goods or service (e.g., the goods ordered). An interaction can include requesting the robot to open its compartment 102, 104 through the customer's app or through a user interface on the robot itself (using, e.g., RFID reader and customer phone, a touchpad, a keypad, voice commands, vision-based recognition of the person, etc.). Upon completion of the delivery (or retrieval, if appropriate), the robot reports completion of the assignment and reports back to the fleet management module for re-assignment.

As further illustrated in FIG. 12, and previously noted, in some embodiments, the fleet management module 120 handles coordination of the robot fleet 100 and assignment of tasks for each robot 101 in the fleet. The fleet management module coordinates the activity and positioning of each robot in the fleet. The fleet management module also communicates with vendors/businesses 204 and customers 202 to optimize behavior of entire system. It does this by utilizing the robot's processor 125 to process the various inputs and outputs from each of the robot's systems and modules, including: the conveyance system 130, the power system 135, the navigation module 140, the sensor system 170, 175, the communication module 160, and the controller 150, to effectively manage and coordinate the various functions of each robot in the fleet.

In some embodiments, the robot may be requested for a pick-up of an item (e.g., a document) with the intent of delivery to another party. In this scenario, the fleet management module would assign the robot to arrive at a given location, assign a securable compartment for receipt of the item, confirm receipt from the first party to the fleet management module, then proceed to the second location where an informed receiving party would recover the item from the robot using an appropriate PIN or other recognition code to gain access to the secure compartment. The robot would then reports completion of the assignment and report back to the fleet management module for re-assignment.

In accordance with aspects of the present disclosure, the central server 110 and/or the fleet management module 120 can include or can be part of a food delivery management system, which will be described in more detail in connection with FIGS. 15 and 16.

Conveyance Systems

Each robot vehicle 101 in the fleet includes a conveyance system 130 (e.g., a drive system with a propulsion engine, wheels, treads, wings, rotors, blowers, rockets, propellers, brakes, etc.).

As noted previously, the robot fleet is configurable for land, water or air. Typical vehicles include cars, wagons, vans, unmanned motor vehicles (e.g., tricycles, trucks, trailers, buses, etc.), unmanned railed vehicles (e.g., trains, trams, etc.), unmanned watercraft (e.g., ships, boats, ferries, landing craft, barges, rafts, etc.), aerial drones, unmanned hovercraft (air, land, and water types), unmanned aircraft, and unmanned spacecraft.

In one exemplary embodiment, a robot land vehicle 101 is configured with a traditional 4-wheeled automotive configuration comprising conventional steering and braking systems. The drive train is configurable for standard 2-wheel drive or 4-wheel all-terrain traction drive. The propulsion system (engine) is configurable as a gas engine, a turbine engine, an electric motor and/or a hybrid gas/electric engine. Alternatively, the robot could be configured with an auxiliary solar power system 135 to provide back-up emergency power or power for minor low-power sub-systems.

Alternative configurations of components to a total drive system with a propulsion engine could include wheels, treads, wings, rotors, blowers, rockets, propellers, brakes, etc.

In some embodiments, the robot fleet is configured for water travel as a watercraft with a propulsion system (engine) that is configurable as a gas engine, a turbine engine, an electric motor and/or a hybrid gas/electric engine and is further configured with a propeller.

In some embodiments, the robot fleet is configured for hover travel as an over-land or over-water hovercraft or an air-cushion vehicle (ACV) and is configured with blowers to produce a large volume of air below the hull that is slightly above atmospheric pressure. The propulsion system (engine) is configurable as a gas engine, a turbine engine, an electric motor and/or a hybrid gas/electric engine.

In some embodiments, the robot fleet is configured for air travel as an aerial drone or aerial hovercraft and is configured with wings, rotors, blowers, rockets, and/or propellers and an appropriate brake system. The propulsion system (engine) is configurable as a gas engine, a turbine engine, an electric motor and/or a hybrid gas/electric engine.

The Power System

In some embodiments, each robot of the robot fleet is configured with one or more power sources, which include the power system 135 (e.g., battery, solar, gasoline, propane, etc.).

Navigation Module

Each robot in the fleet further includes a navigation module 140 for navigation in the unstructured open or closed environments (e.g., digital maps, HD maps, GPS, etc.). In some embodiments, the fleet 100 relies on maps generated by the user, operator, or fleet operator, specifically created to cover the intended environment where the robot is configured to operate. These maps would then be used for general guidance of each robot in the fleet, which would augment this understanding of the environment by using a variety of on-board sensors such as cameras, LiDAR, altimeters or radar to confirm its relative geographic position and elevation.

In some embodiments, for navigation, the fleet of robots uses internal maps to provide information about where they are going and the structure of the road environment (e.g., lanes, etc.) and combine this information with onboard sensors (e.g., cameras, LiDAR, radar, ultrasound, microphones, etc.) and internal computer processing to constantly determine where they can safely navigate, what other objects are around each robot and what they may do. In still other embodiments, the fleet incorporates on-line maps to augment internal maps. This information is then combined to determine a safe, robust trajectory for the robot to follow and this is then executed by the low level actuators on the robot.

In some embodiments, the fleet relies on a global positioning system (GPS) that allows land, sea, and airborne users to determine their exact location, velocity, and time 24 hours a day, in all weather conditions, anywhere in the world.

In some embodiments, the fleet of robots will use a combination of internal maps, sensors and GPS systems to confirm its relative geographic position and elevation.

In some embodiments, the autonomous fleet is strategically positioned throughout a geographic region in anticipation of a known demand.

Over time, a user 200 and/or a vendor 204 can anticipate demand for robot services by storing data concerning how many orders (and what type of orders) are made at particular times of day from different areas of the region. This can be done for both source (e.g., restaurants, grocery stores, general businesses, etc.) and destination (e.g., customer, other businesses, etc.). Then, for a specific current day and time, this stored data is used to determine what the optimal location of the fleet is given the expected demand. More concretely, the fleet can be positioned to be as close as possible to the expected source locations, anticipating these source locations will be the most likely new orders to come into the system. Even more concretely, it is possible to estimate the number of orders from each possible source in the next hour and weight each source location by this number. Then one can position the fleet so that the fleet optimally covers the weighted locations based on these numbers.

In some embodiments of the robot fleet, the positioning of robots can be customized based on: anticipated use, a pattern of historical behaviors, or specific goods being carried.

Sensor Systems

As noted previously, each robot is equipped with a sensor system 170, which includes at least a minimum number of onboard sensors (e.g., cameras (for example, those running at a high frame rate akin to video), LiDAR, radar, ultrasonic sensors, microphones, etc.) and internal computer processing 125 to constantly determine where it can safely navigate, what other objects are around each robot, and what it may do within its immediate surroundings.

In some embodiments, the robots of the robot fleet further include conveyance system sensors 175 configured to: monitor drive mechanism performance (e.g., the propulsion engine); monitor power system levels 135 (e.g., battery, solar, gasoline, propane, etc.); or monitor drive train performance (e.g., transmission, tires, brakes, rotors, etc.).

The database 516 can store the food orders and can also store information for each of the autonomous robot vehicles 520, including, for example, vehicle ID, equipment inventory, and food inventory for the vehicle. Different vehicles 520 may have different equipment and food offerings. For example, one vehicle may include equipment such as a freezer module, an oven module, and a beverage dispenser, and may include food such as pizza and container beverages. Another vehicle may include equipment such as a coffee maker and a microwave, and may include food such as microwave breakfast sandwiches. This information is stored in the database 516 of the food delivery management system 510. The database 516 can also store the location of each autonomous robot vehicle 520. As described above herein, each vehicle 520 can include GPS navigation capability. The autonomous robot vehicles 520 can communicate their locations to the food management delivery system 510, which can store the location information in the database 516. The listing of database information in FIG. 18 is exemplary, and other information regarding food orders or autonomous vehicles can be stored in the database 516.

With continuing reference to FIG. 18, when the food delivery management system 510 receives a food order, the system 510 determines which autonomous vehicles 520 may be capable of fulfilling the order. In particular, in accordance with aspects of the present disclosure, the food order can specify food items to be heated en route during delivery. The food delivery management system 510 can access the database 516 to access the equipment inventory and food inventory for the autonomous vehicles 520, and to determine which vehicles 520 include the ordered food item and the equipment for heating the food item. In various embodiments, the food delivery management system 510 can additionally access the location of each vehicle 520.

In various embodiments, the food delivery management system 510 can communicate the food order to one or more of the eligible vehicles 520 that include the food item the necessary heating module. In various embodiments, the food delivery management system 510 can assign the food order to the eligible vehicle 520 that is closest to the delivery destination. In various embodiments, the food delivery management system 510 can assign the food order to the eligible vehicle 520 that has the fewest number of food orders. In various embodiments, the food delivery management system 510 can assign the food order to the eligible vehicle 520 that has the optimal balance of distance and number of food orders for delivery. In various embodiments, the food delivery management system 510 can communicate the food order to one or more eligible vehicles 520, and each eligible vehicle 520 can either accept the order or reject the order. In various embodiments, the food delivery management system 510 can broadcast the food order to all eligible vehicles 520, and the eligible vehicles 520 can respond with a “bid” for the food order, such that the vehicle 520 with the highest bid can be assigned the food order. In various embodiments, an autonomous robot vehicle 520 that is assigned a food order can respond to the food delivery management system 510 with a delivery time estimate for the food order, and the food delivery management system 510 can communicate the time estimate to the customer device 540. The various ways of assigning a food order to an autonomous vehicle are exemplary, and other ways of assigning a food order to an autonomous vehicle are contemplated.

In accordance with aspects of the present disclosure, the food delivery management system 510 can analyze historical food orders to identify food ordering patterns. For example, there may be recurring peak times when particular food orders are placed, such as coffee orders between 7:00 AM and 8:00 AM, or peak times when particular food orders are delivered to certain locations, such as pizza orders for delivery to a local high school between 11:30 AM and 12:30 PM. In various embodiments, the food delivery management system 510 can preemptively instruct one or more robot vehicles 520 to preemptively prepare food/beverage orders before the orders are actually placed by consumers. In various embodiments, the food delivery management system 510 can communicate actual food orders to the robot vehicles, with the food orders having no assigned customer. If a customer places a food order that has been preemptively assigned to a robot vehicle 520, the food delivery management system 510 can associate the customer with the preemptive food order and communicate the customer information to the robot vehicle 520. The disclosed embodiments are exemplary, and other variations and embodiments of implementing food order analytics and forecasts, and implementing preemptive food orders, are contemplated to be within the scope of the present disclosure.

In accordance with aspects of the present disclosure, and with reference to FIG. 12, the following will describe control and processing of an autonomous robot vehicle that receives a food order. As shown in FIG. 12, an autonomous robot vehicle includes a robot processor 125. The robot processor 125 executes instructions stored in a memory (not shown) to perform the operations described herein, including determining a travel route for delivering food orders, and scheduling food orders to particular preparation modules, among other things. In various embodiments, an autonomous robot vehicle that receives a food order for a delivery destination can use the navigation module 140 to determine a travel route that includes the destination. In various embodiments, the vehicle can evaluate different possible travel routes provided by the navigation module 140 and can select a travel route that provides sufficient time to heat the food item of the food order before reaching the delivery destination. For example, an autonomous vehicle may select a route that delivers a later food order first, to provide sufficient time to heat an earlier food order. Accordingly, the autonomous vehicle can schedule the food orders to the preparation module(s) based on the route selection. In various embodiments, an autonomous vehicle may include multiple preparation modules and may schedule multiple food orders to different preparation modules.

In various embodiments, the robot vehicle includes multiple preparation modules and has the capability to concurrently prepare food and/or beverages for multiple customers. In various embodiments, the processor 125 can schedule the preparation of food orders based on the estimated time to arrive at the customer location and/or based on the preparation time for each food order. If multiple preparation modules are available and the optimal scheduling indicates that more than one food order should be prepared concurrently, the processor 125 can schedule the food preparation accordingly.

With continuing reference to FIG. 12, after the processor 125 has selected a travel route, the processor 125 controls the conveyance system 130 to travel the travel route. During the travel, the processor 125 controls the securable compartments 102, 104 based on the schedule assigning food orders to preparation modules. The securable compartments 102, 104 can be any of the compartments or sub-compartments disclosed herein, such as the compartments or sub-compartments shown and described in FIGS. 2, 7-10, and 13-16. For example, while traveling the travel route, the processor 125 can control a conveyor (330, FIG. 14) to convey a food item from a storage module (such as a refrigeration/freezer module) 102, 104 to a preparation module, such as an oven module, and can control the preparation module to prepare the food item while travelling the travel route. When the autonomous vehicle reaches the delivery destination, a customer can retrieve the food order in the manners described above herein.

In various embodiments, the processor 125 can control the conveyance system 130 based on various parameters. In various embodiments, if travel time is less than food preparation time, the processor 125 can control the vehicle to delay its arrival at the customer location by, for example, parking on street-side parking for a period of time or circling around a neighborhood for a period of time until the food preparation is completed or is close to being completed. In such embodiments, the processor 125 can control the preparation modules to begin food preparation as soon as a module is available. In various embodiments, if travel time is greater than food preparation time, the processor 125 can control the preparation modules to delay food preparation until the robot vehicle is closer to the customer location. In such embodiments, the processor 125 an control the preparation modules to begin preparing food when the remaining time to reach the destination is longer than the time to prepare the food by a predetermined threshold. For example, the predetermined threshold can be a duration (e.g., remaining travel time is five minutes longer than food preparation time), or can be a percentage (e.g., remaining travel time is 110% of food preparation time), or can be another threshold. In various embodiments, even if travel time is greater than food preparation time, the processor 125 can still control the preparation modules to begin food preparation early and then keep the food at the proper temperature by controlling the temperature of the preparation modules.
